SPECIFICATION forming part of Letters Patent No. 663,937, dated December 18, 1900- Application filed February 2'7. 1900. Serial No. 6,695. (No model.) v

[o @ZZ wtont it' may concern:

Beit known that I, CHARLES B. SCHOEN- MEHL a citizen of the United States, and a resident of Waterbury, in the county of New 5 Haven and State of Connecticut, have invented certain new and useful Improvements in Galvanic Batteries, of which the following is a specification.

This invention relates to new and useful 1o improvements in-closed-circuit `galvanic batteries wherein oXid of copper and a suitable fiuid make up the several principal elements thereof.

The object of my invention is principally I5 to provide a battery the condition of which may readily be detected Without the use of a gage or meter, thereby avoiding loss of time when inspecting. The above is accomplished by the employment of a transparent jar and 2o locating the copper element adjacent to the inner wall thereof, so that its condition may be seen at a glance. I further provide means whereby the copper employed is uniformly distributed within and against the inner wall of the jar, so as to insure a uniform action upon all sides and whereby an examination of one side of the jar may be relied upon as representing its true condition.

With the above object in view I provide 3o the novel construction and combination of parts set forth in the accompanying drawings, forming a part of this specification, and upon which similar characters of reference denote like or corresponding parts throughout the several figures, and of which- Figure l shows a central vertical sectional View of my novel battery complete. Fig. 2

is a plan View of Fig. l, the cover of the battery being removed. Fig. 3 shows a sectional 4o View similar to that illustrated in Fig. l, but

containing a modified form of the oxid-of-copper chamber. Fig. 4 is a detail sectional plan View of the lower portion of a jar containing a further modification of the means for producing an oXid-of-copper chamber of uniform thickness. Figs. 5 and 6 show a plan and a cross-sectional view, respectively, of a construction containing a double series of vertical pockets.

Referring in detail to the characters of reference marked upon the drawings, A indicates the jar, which, as before stated, is preferably formed of glass, and B its cover,which may be of the usual metallic construction. Within the jar I locate a perforated cylindrical metal wall C, which is designed to retain the oxidof-copper elements against the inner wall of the jar in a manner to permit of its inspection from the exterior. This perforated cylinderis specially constructed and so arranged 6o that when placed into the jar it centers itself and needs no special adjustment to produce a chamber or series of chambers D of uniform depth and thickness upon all sides, thus per-` mitting a uniform quantity of copper oXid to be contained therein, as before stated. In Figs. l and 2 I have shown this perforated cylinder consisting of a series of vertical corrugations, each of which, in conjunction with the jar,forms a separate vertical compartment 7o for the reception of oxid of copper, as will be apparent. These compartments are of uniform size and shape and are equally subjected to the electrical iniiuences. Consequently they are uniformly consumed, the process of which is rst apparent by the coloring which begins at the top of said copper and gradually works down through the body thereof until it is entirely consumed. This perforated cylinder is provided with a wire E, which extends 8o lup through and is insulated from the cover B,

before mentioned, by means of suitable insulating-Washers F F, as is clearly shown. Nuts G G serve to clamp these washers against the cover, and a thumb-nut H is provided forthe service-wire.

Upon the inside of the perforated cylinder I attach la suitable number of cleats I to the convex portion of the adjoining oorrugations, thus spanning the concave portion thereof in 9o a manner to form a rest for a porcelain support J, as clearly appears in Figs. l and 2. Tllese porcelain rests When properly located serveto retain a zinc element K central of the basket and at a uniform distance therefrom. This zinc is also provided with a Wire L, which extends up through the cover and is insulated therefrom through the medium of washers and nuts, asin the instance of the previously-mentioned wire, attached to the Ioo perforated cylinder. This wire L is also provided with a th umb-n ut M, by means of which a second ield-Wireis attached. The completion of the battery is effected bythe employment of a suitable exciting'fluid.

In Figs. 3 and 4. I show perforated cylinderswhich when inserted produce a single chamber for the oxid of copper, which is of uniform diameter upon all sides. In Fig. 3 it Will be seen that this is accomplished by forming the cylinder smaller at one end than at the other, the lai-gestor bottom end being of a diameter equal to that of the interior of the jar, thus insurin,.,r the proper centering of the cylinder Within the jar and producing a chamber thicker at the top than at the bottom, but of a uniform thickness at opposite sides. The perforated cylinder in Fig. 4 is shown partially inclined ,but the essential feature in this construction is the turning ont of a flange N at the bottom of the cylinder, the peripheral edge of which is of a size that will snugly fit into the interior of the jar.

In some instances ll elect to use both the corrugated cylinder C (shown in Fig. 2) and a plain cylinder, in some respects similar to that shown in Fig. 4, by placing the latter inside of the former, thus producing a double series of compartments D and D', which construction gives more room and is easier to vfill Wlth copper oxid. 3o

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

yl. The combination in a battery of the class described of a transparent jar, a perforated corrugated cylinder fitted into said jar producing an outer series of pockets, a perforated cylinder interior of said corrugated cylinder forming an inner series of pockets, a

' depolarizing agent in said pockets, a zinc,

means for supporting the same and a binding-Wire attached to said zinc.

2. In a battery of the class described, the combination with a transparent jar, of a perforated cylinder therein provided with a series of corrugations to retain it at a uniform tact-wire, and means for supporting said zinc.

3. In a battery of the class described, the combination with a transparent jar, of the perforated corrugated cylinder adapted to snugly t into said jar and be retained at a vuniform distance from the same, a connecting-Wire from said cylinder and series of cleats secured to the interior of said cylinder, porcelain rests supported on said cleats, an oXid-of-copper element, a Zinc element resting upon said porcelain rests and a binding-wire attached to said zinc.

4. The combination in a battery of the class i described, of a transparent jar, a perforated cylinder fitted into the interior of said jar, extensions of said cylinder forming a series of pockets between said cylinder and jar, an oXid-of-copper element in said pockets, por. celain blocks attached to the interior of said cylinder, a zinc resting upon said blocks and a connecting-Wire from said zinc.

5. In a battery the combination with a transparent jar of a perforated cylinder, eX- tensions of said cylinder to engage the vertical Walls of the jar and retain it at a uniform distance from the same to form one or more pockets of an equal diameter upon all sides, an oXid-of-copper element Within said pocket, a zinc element, suitable insulatingblocks supporting said zinc at a uniform distance from the cylinder, connecting-Wires from the zinc and cylinder with suitable binding-screws attached, substantially as shown and described.
